SPEED-RECORDER.

' ing, thespeed being noted either directly as iss such or indirectly as distance traveled and time occupied in traveling the same, or it may be noted in both modes. When the speed is noted directly as such, either the distance traveled at each speed or the time during which each speed is maintained may be noted. When speed is noted both directlyas such and indirectly in terms of distance and time,'the d istance. traveled and the time of traveling at each speed wouldnaturally both of them a be noted. Apparatus similar to" that for recording thezspeed of an automobile can be used to record the speed of other machinery.

The invention also relates to apparatus analogous 'to speed-recorders in' that they make a record (or a succession of records) on anappropriate blank by means of an appropriate marking instrument andcomprise means for supporting such blank and instrument and for suitably moving one or other,

or both, of them. I

In the present invention in itsmost complete form the recorder consists of means for supporting and moving are'cord-blank in the form of a tape in front of a reservoir-pen which bears constantly against the tape, and is actuated in the plane of the face of the tape at place of marking transversely to the direction of its motion; but modifications can be made 'within the spirit of the invention. 3

Parts of the invention, moreover, can be used separately, and each (part, improvement, or combinatlonfinolude "1n the invention is I: intended to be secured for all the uses for which itcan, withor without modification,.

Recorder's have been devised' hereto ore with record-blanks in other forms (as disks or cylinders,'for'e'xample) as well as in the formfof tapes, and some of them have ,used othenformsof marking instruments (as pencils,- Styluses, punches, perforating-points, or type, for example) as well as;

' those in the form of pens and have'had the marking instrument act upon the recordblank otherwise (at intervals, for example) as -well as in -a continuous manner and have had the marking instrument actuated in other directions (as at right angles to the face of record-blank at place of marking) as well as in the plane of said face transverse to the direction of the blanks motion. They have also had the means for supporting the recordblank and marking instrument and for, ima parting motion thereto arranged. with reference 'to the purpose for which the recorderis designed. Thus where a record of something besides speed has been desired (as variations of temperature or telegraphic or other signals, for example) motions have been imparted to the record-blank and the marking mstrument, respectively, from devices the position of one at least of which is dependent upon the thing to be recorded. Where speed is directly or indirectly to be recorded, the requisite motions arederived, respectively, from devices whose ositions are ependent one upon a time an the other upon'a distance element, and where the positions of one of said devices are dependent (like acentrifugal governor, for example) upon speed the positions of the other may be ependent either upon a time or, a distance element,

because s eed combines elements of both time and ista'nce.

The invention is believedto be applicable in some one or more of its parts -to very many, at least, of the forms of recorders heretofore devised,,as well as to that form which, i i as indicated above, embodies the invention most completely. It will suffice, however, I

to exhibit it as thus embodied and to show some of the variations which can be made, while preserving what is indicated above as the most complete form of the present inven- Thus means will be shown for moving tion. the record-blank in one variety by a timepiece andinanother by a device whose movement represents distance, while means for actuating the marking instrument will be illus trated in three variations, in one of whlch it I is actuated .by a device whose movement represents distance, in the second of which it is actuated by a timepiece, and in the third of er'nor.: Should it be desired-to record the speed both directly and indirectly, one way to accomplish it would be to use two marking instruments in connection with means for .which it is actuated by a centrifugal. govsupporting and moving a record blank or is inserted through a journal-bearing in the blanks, which means would, in part at least, be the same for both instruments, one instrument being actuated by a speed-indicator (as azcentrifugal governor, for example, or

other known or suitable speed-indicator) and the other instrument by a timepiece (in case the movement of the record-blank should depend upon a device whose movement represents distance) or by a distance device, (in case the movement of the record-blank should depend upon a timepiece.) Inasmuch as each of these modes of moving a record-blankwill be illustrated, as well as each of the three modes of actuating a marking instrument,namely, by a speedindi cator, by a distance device, and by a timepieceit'will only require an arrangement and combination in the manner just referred to of what is thus illustrated in order to have two styles of apparatus for recording speed both directly as such and indirectly in terms of time and distance-namely, one style in which the marking instruments shall be actuated, one by a speed-indicator and the other by a distance device, and the other style in-which they shall be operated, one marking instrument by va speed-indicator and the other by a timepiece.

The invention includes all and singular the new, useful, and original parts, improvements, and combinations herein set forth.

Fig. 3 is a plan 'view of the same with cover and some additional parts removed. Fig. 4 is a front view of the same recorder with cover removed.

view, partly in vertical section, of all but one of the parts shown in Figs. 2 and 4 and OIDlllv' ted from Figs. 3 and 5.. Fig. 7 is a view of part of the same recorder, partly in plan and partly in horizontal section. Fig. 8 is a front view of another variety of the same general form of speedrecorder, also within the invention; and Fig. 9 is a similar view of a third variety, likewise within the invention.

The. frame of the apparatus consists, as shown, of a'box having ends a, back I), bottom-c,--cover. d, and division-plate e, this last being parallel with the bottom. The ends a are provided with upright fiangesf, to which the back b is fastened, with horizontal flanges g, to which the bottom c is fastened, and with horizontal-flanges h,- to which the division-plate e is fastened. The cover (1 is hinged at j and is provided with a look 'i. The flexible shaft k, which transmits motion to the speed-recorder, terminates, as shown, in aspindle Z, on'which the gears m in. and collar 0 are secured by set-screws. The spindle record is to be made.

lug on the adjacent flange g and into a similar bearing in the lug q on the adjacent flange h.

The gear '11 communicates motion to gear 1", forming part of a counter s of known or of any suitable construction secured on the adjacent end a of the box outside of the latter.

As shown in Figs. 1-7, the worm-gear m communicates motion through an intermeshing gear t (indicated in. dotted lines in Fig. 4) to the horizontal shaft a, which is journaled in'lugs o w on the ends a of the box and which communicates motionto the upright shaft 00 through the bevel-gears y and z. The shaft w is journaled in lugs W3 4 on the adjacent end ct of the box. cates motion through an intermeshing gear 6, Figs. 2, 4, and 5, to the horizontal shaft 7, which is j ournaled in lugs 8 and 9 on the adj acent end a of the box and which at its outer end carries the star-wheel 10 for imparting a reciprocating movement to the marking instrument 11 of the recorder. As shown, thisinstrument is in the form of a pen 11, Figs. 1 and 2, provided with an ink-reservoir 12, and it is mounted on a leaf-spring 13, which con stitutes the long arm of a lever whose shorter arm 14 is acted upon by the star-wheel. The marking instrument,11 is thus actuated by a distance device10, or, in other words, by a device v10 whose movement represents the distance to be recorded, for the turns of said device or star-wheel 10 are in a fixed roportion to the revolutions of shaft 7c, and y con- The pen 11 may be of any known or suitable construction and is shown as consisting of a metal trough beveled on top (see Fig. 2) at'its inner end, (or, in other words, at its point.) It is supplied with ink which ad heres to the metal (brass) sufliciently to be drawn off slowly by adhesion to the surface of a moving sheet or tape of paper on which a Such ink is a known commercial article.

At its outer end the pen is connected with the reservoir 12, having spaces below the level of the pen, from which spaces the ink-is raised to feed the en. As shown, the pen is placed in the mid 1c of the reservoir between two intercommunicating. ink-spaces whose bottoms meet like the sides of an inverted V, and the pen communicates with the interior of the reservoir through the opening 11', Fig. 6, at about the apex of the V. As the pen is raised and lowered by star- A worm-gear 5 communioneor more ink tilted in consequence of its movement in the arc of a circle with the fulcrum of lever 13 14 -as a center; but thebottom 0-: each inkspaee at one time or another is below the level of the pen-feed, or, in other words, below the level to which the ink must be raised in order to supply the en. With the feedopening 1 1 in a vertica Wall of the reservoir, as shown, such level must be at least as hi h as the bottom of the opening 11-. By t e tilting of the reservoir 12 the ink-space on each side of the opening 11 is alternately raised and lowered with reference to the other, and the ink consequently flows from one ink-space to the other past the pen-feed opening 11 Enough ink passes through the opening 11' to keep the pen 11 sup lied. on an automobile the jolting to whic the recorder is subjected throws up the ink from the lower-level ink-spaces and so supplies the pen with ink, this action being independent of the movement of the pen-reservoir by the machinery of. the recbrder.

There is a special advantage in having inkspaces on opposite sides of the pen, in that the ink to su ply the pen may flow from one of them to t e other, and there will thus be a smallerrising at the pen feed opening 11. This advantage would accrue irrespective of the inverted-V shape of the reservoir-bottom, since with two spaces of any shape the tilting or jolting of the reservoir (suitably supplied with ink) might cause the ink to flow from one space to the other. It would also to a certain extentaccrue irrespective of the position of both spaces below. the level of the pen-feed, since the ink might spread into a space Whose bottomshould not be below said level. The broad advantages of a lower-level reservoir moreover, are not dependent .upon having ink-spaces on opposite sides of the pen nor on having more than one ink-space. Y

The lever 13 141 is fulcrumed on the post 16, which is united to an upright plate 17,

and this latter is provided with a flange 18,

by which said plate 17 and post 16 are secured to the division plate? of *thebox, The upright plate 17 on its outer'face, below-the flange 19, affords a shallow recess for receiving the ta e 20, on-which last the record is made. T e tape is drawn a ainst the face of late 17 by the tape-hol 'ng and tapefee ing means, which are'best in the form shown, and in this form consist of a supplyspool 21, a pair of feed-rollers 22 23, and a receiving-reel 24 for the marked tape. A sprin -held'presser 25 is also best employed to ho d the tape 20 against the face of plate 17, It is fastened onan arm 26, which is .pivotally' mounted on the end a of the box by means of ournal-pin 262 and which when in an upright position is acted upon by the leaf-spring27 in the direction to hold the presser against the tape. To facilitate the insertion and withdrawal of the ta e 20,'the arm 26, with the presser 25, can "e turned down, the spring 27 then tending to hold it out of the way in consequence of the extremity of the arm 26 acted upon by the spring assin' from a position in front of to one be ind tlie pivot of arm 26. The elasticity of the pen-supporting arm 13 allows the pen and its reservoir to be withdrawn out of the path of the presser when desired.

The supply-spool 21 is placed loose at? out a s indle 28 on the horizontal plate 29, which is astened to and supported by the plate 17.

Thefeed-rollers 22 23 best have roughened surfaces formed integral in the rollers say by pressureagainst a file or rough-surfaced die'.in order tonip the tape more firmly. One roller 22 is mounted on a stationary stud 30, screwed fast at its lower end in the division-plate e. The other roller 23 is carried by one end of a spring-plate 31, whose otherend is fastened to the back 5 of the box. By mounting ofie of the rollers on a spring-plate it canbe moved aside to facilitate insertion of the tape between the'feed-rollers and its removal therefrom. It might suffice to allow one of thefeed-rollers to revolve by friction; but it. is considered preferable to rotateboth of them positively, and they are therefore shown as provided with intermeshing gears 32 33.

In the speed-recorder of Figs. 1-7' the feed-rollers 2223' are rotated by a clockwork, while, as before stated, the pen ,11 is moved up and downby the revolutions of shaft k, and consequently in this variety of the new or improved recorder the pen 11 tracesv on the tape 20 a straight longitudinal line when the shaft is is stationaryan'd a zigzag line when the shaft 76 revolves. Apart straight and part zigzag line, such as might be formed, is

indicated at 34 in Fig. I. The higher the speed of the shaft k the more nearly vertical do the elements of line 34 become. By suitable adaptation of gearing each stroke of pen 11 up or down can represent any desired distance traveled, and the tape can be moved at any desired speed; .but assuming that each single pen-stroke'represents a 'quarter of a mile'and that one space between the'vertical division-lines on. tape 20' passes the'pen each minute, then if each single pen-stroke takes place recisely in one of said spaces (or in an equa distance) the speed recorded will be a quarter-mile a minute or fifteen miles an hour. Should thiss eed be doubled, each single pen-stroke wil occupy only half a minute space, theangle which each pen-stroke'will make with the vertical being only about half as large as that made-by the former pen-strokes. I The surface on the lever-arm 14, against which the star-wheel (or as near so as practicable) when the shaft kis revolved at uniform speed. Whenever the speed changes, a change in the vertical angle of the strokes naturally takes place at the time when the change in speed occurs. Apart, however, from the straightness of the up-anddown lines drawn by the pen the of the pens movement the distance traveledin any period of time can be ascertained.

' For rotating the feed-rollers 22 23 an ordinary clockwork is shown supported under and by the division-plate e, with the arbors of the clockwork in a vertical .position. Thi

clockwork is shown with two springs 36 on the same, winding-arbor 37,. because thisclockwork was originally made foran ordinary timepiece, and the spring 36 had to be' added to supply the power to feed the tape; but it is not considered advantageous to have more than one spring. The minute-arbor of the clockwork is extended through the division-plate e and carries the gear-wheel 38, which drives the feed-roller 22 through the intermediary of an idler 39. It also serves to revolve the reel 24 by intermeshing with the gear 40, Figs. 3'and 5, having 'a friction I connection with the reel 24. The journalrollers 22 23.

pin 41 for both the car 40 and the reel 24'is formed 'by a shoulered screw tapped into the division-platee, as indicated in dotted lines *in Fig. 5. The gear 40 carries a forked spring 42, Figs. 5 and 7, which embraces the hub of reel 24 and turns it by friction. The feeding of the tape isfefi'ected by the feed- The reel 24-merely winds up the tape as fast as it is fed to it by said. rollers. The gearing is so proportioned that it. tends to revolve the reel 24 site greater peripheral speed than that of the rollers 22 23, .so as to keep the tape between-said rollers and the reel 24 under the slighttension afforded by the friction of spring 42. The reel 24- is best made with a slit .43 to receive the end of the tape. It is also shpwn as provided with pins 44 for turning it by hand when desiredias,"

for example, in inserting 'atape. To facilitate the removal of the tape from the reel,

the Ia'tterhas notches in its periphery, Figs.

2 and 3,'and is provided with a stripper-plate 45, with projections 46 into the notches in the reel24, By taking hold of the strip erplate at its ed es and raising it the r'ol of ta e on the reefcan be ushed off bodily.

' Trijthe variety-of t e new or" improved 601s shown as the bevel-gears 48 49, and the shaft 47 com municates motion through worm-gears 50 51 to the upright shaft 52, which carries the feed-roller 22 on, its upper end. The feedroller 23 is supported and operated as before described. The tape-sup orting means are as before described; but t e vertical. di-

VlSlOIlS of tape 53 instead of being representative of time are representative of distance. The recording-pen, with its reservoir'12, is mounted on a leaf-spring 13, which constitutes the long arm of a lever fulcrumed on post 16, as before described. In Fig. 8,

however, the short arm 54 of this lever is arranged to be lifted in equal periods of time say once a minute or as often as preferred. It has a projection 55, which overlies a crown of teeth 56 on the gear-wheel 38 and which is kept in contact therewith by the s iral ten sion-spring 57. As each tooth of t e crown 56 passes underand in contact with the projection 55 it raises the'lever-arms 54 13 and the recordingen and then allows the same to descend. hus while the shaft 7c and feed-rollers '22 23 are "turning .the tape 53 moves at corres onding'speed and the en makes a zigzag ine on the tape, the stro es of which line more nearly approach the vertical the slower the speed. I When the shaft it stops, the recording-pen moves up and down in a vertical (slightly 'curved) path. Assuming that the en makesasingle stroke up or down each half-minute, then under this assumption each reversal ofits motion will take place when the tape 53 has in half a minute. y counting the number of reversals the time occupied (stops ex cluded) in traveling any particular distance can be ascertained, Stoppages will also be indicated, but not their duration.

. In the variety of the new or improved speed-recorder shown in Fig. 9 the-recordingpen is operated by a centrifugal governon. As shown, the governor-balls 58 are mounted loosely on arms 59' of the shaft 60, which arms restrain said balls against-transverse movement, so that when exposed to jolts and lurches there is no tendency to force the ballstoward or away from each other,- because the only-motions permitted by thearms are those of separatlon and approach; and' in such motions the effect of a jolt or lurch on one ball-is counteracted by' its opmoved a distance re resenting that traveled posing effect on the other ball. Springs 61 i tend to draw the balls 58 inward against the action of the centrifugal force. he shaft being revolved by the gear 62 on spindle-l of shaft 7c through the intermediary of the pinion 63 intermeshing with the gear 62 and the .gear 64 turning with pinion 63 and intermeshing with the pinion 65 on the shaft 60. This last is shown as having a step-bearing in the lug 66 on the adjacent box-head a and a cap ed side bearing near its upper end in the ug 67 on the same head a. The motion could be con- .veyed to the marking instrument from governor-balls by other devices; but, as shown, lazy-tongs are used for the purpose. They are believed to have special advantages. The crossed lever-arms 68 of the lazy-tongs are pivotally connected at their lower ends with the governor-balls, preferably by the same pins 69 to which the ends of springs 61 are attached. At their crossing they are pivoted on the slide 70, which is movable vertically in a guideway in the shaft 60. At-

' pen up when the balls approach each other and raise the slide 72, and the springs 75 ull it down when the balls separate and ower the slide 72. The tape 76 can either be provided with time divisions and-be fed by a clockwork, as is the tape 20'of Figs, 1, 2, and.4, or it can be provided with distance divisions and be fed by connection with the shaft 7c, as is the tape 53 of Fig. 8. As shown in Fig. 9, it provided with vertical time divisions and the feed-rollers 22. 23 are driven by clockwork. The tape 76 is provided with longitudinal lines to enable the s eed-recorder to be more easily perceived hus each horizontal line countin from top downward "may represent an acce eration of five miles an hour or whatever acceleration it may be preferred to indicate, the governor being adjusted to cause the recording-pen to move through corresponding vertical intervals as the speed of the shaft k varies.

Th8 tapes 20 and 76 each of them record data showing the day, hour, and minute at which each mile was passed over, as well as the speed during each mile and the total number of miles. The ta e 53 records the speed during each mile an the total number of miles; but the time of day at which each mile. passed over can be ascertained only in case the time of starting or stopping should be noted otherwise. I

In Fig. 9 the reservoir 12 isnot tilted by the machinery; but reliance is had upon movements from outside (as u on the jolting of therecorderwhen carried y an automobile) to raise the ink to the level of the penfeed. It is evident, however, that a reservoir arran ed to be tilted by machinery forming part c the recorder, as well as one not so arranged, could be actuated either by a centrifugal 'governorthat of Fig. 9, for ex- .ample-or by a timepiece, as in Fig. 8, or

by a distance device, as in Figs. 1-7. The

en 11 and reservoir 12, mounted on a.

eaf-spring 13,;-which should constitute the arm of a lever, .as in Fig. 8 and also in Figs.

1-7, could, fo r example, be actuated by a pin 73, which should be controlled by a centr1fugal governor, as in Fig. 9, and in such case the spring 13, reservoir 12, and pin 73 could be depressed by a spiral tension-spring arranged as s'hown for the spring 57 0 Fig. 8:

The coverd, which constitutes both the top and front of the box a b c d and which, as mentioned above, is hinged at to the body of said box, is best provided with a curved glass panel 77, 1, to allow the record on the tape to be seen.

The operation of each variety shown of the new or improvedrecorder can be understood from the preceding. description but a brief In all of recapitulation may not be amiss. them asthe tape is'unwound from spool 21 by the pull of the rollers 22 23 it passes along the slightly-recessed face of plate 17 andis marked with a line traced by the recording-pen 11, Fi 52. Referring to Figs. 1-7, when the shaft is revolved the pen 11 moves ,up' and'down across the tape 20, making Each reversal takes thereon a zigzag line. place when the, shaft 7c has made apredetermined number of'revolutions, and it thus indicates a certain distance traveled. The longitudinal space on the tape 20 between reversals shows the time occupied in traveling said distance, and thus indirectly gives the speed. The tape 20 being printed with the days and the hours and minutes of each 'day the distance traveled during any day or part, of a day can be ascertained by counting the reversals during the corresponding space on 'the tape 20.

Referring to Fig. 8, the ta e 53 is moved by rollers which are actuated horn the shaft 1a. For a given number of revolutions of shaft (representing a certain distance traveled) the tape 53 is fed a predetermined distance, and the recording-pen attached toreservoir 12 traces a zigzag line, each reversal of which takes place after a definite interval of time. Thus the longitudinal distance traced on tape 53 between reversals shows the distance trav: eled in a unit time interval, and consequently gives, the speed. 'To ascertain the distance traveled during a particular day or part of a day, it-is necesssary to make a separate note of the time of each start .or sto If the start should all beknown, the num er of reversals in the'zigzag line will enable the times of stopor if the stops are known reckoning backward will we the times of starting, and the'time of traveling any intermediate distancecan be-similarly reckoned out.

Referring to Fig. 9, the tape 76 1S fed by clockwork-actuated feed-rollers and is marked by a straight line except when changes of speed occur, this effectbeing due to the'adj'ustment of pen 11 and reservoir 12 by a governor, whose balls 58 remain at the same distance from the center when the speed is uniform and separate from or approach toward each other when the speed increases or diminishes. The speed at each movement is given directly, alsothe time mterval during which each speed continues, so that 'the distance traveled during any day or part of a day can be ascertained.

In consequence of official requirement of division the recording-pen, which is believed. to be new in and of itself and which was originally claimed herein irrespective of other parts, is made the subject of my application,
